aoss - Wrapper script to facilitate use of the ALSA OSS compatibility library.
aoss osscommand [arguments]
aoss is a simple wrapper script which facilitates the use of the ALSA OSS
compatibility library. It just sets the appropriate LD_PRELOAD path and then
runs the command.
This is useful in cases where routing settings (which can be made in your
.asoundrc file) need to be applied to commands that use the OSS API.
Examples of asoundrc configuration:
pcm.dsp0 { type plug slave.pcm "hw:0,0" }
or
pcm.dsp0 { type plug slave.pcm "dmix" }
In the above configuration examples, the pcm.dsp0 definition is used to wrap
calls do /dev/dsp0. You can also wrap usage of /dev/dsp1, /dev/dsp2, etc. by
defining pcm.dsp1, pcm.dsp2, etc..
The PCM name to open can be given explicitly via
ALSA_OSS_PCM_DEVICE
environment variable, too. This overrides the default
dsp0, etc.
Note on mmap: aoss mmap support might be buggy. Your results may vary when
trying to use an application that uses mmap'ing to access the OSS device
files.
